FEATURES
4096 bits of nonvolatile dual-port memory
including real time clock/calendar in binary
format, programmable interval timer, and
programmable power-on cycle counter
1-Wire interface for MicroLAN
communication at 16.3kbits/s
3-wire host interface for high-speed data
communications at 2Mb/s
Unique, factory-lasered and tested 64-bit
registration number (8-bit family code +
48-bit serial number + 8-bit CRC tester)
assures absolute traceability because no two
parts are alike
Memory partitioned into 16 pages of 256-bits
for packetizing data
256-bit scratchpad with strict read/write
protocols ensures integrity of data transfer
Programmable alarms can be set to generate
interrupts for interval timer, real time clock,
and/or cycle counter
16-pin DIP, SO, and SSOP packages
Operating temperature range from -40°C to
+85°C
Operating voltage range from 2.8V to 5.5V

DESCRIPTION
The DS2404 EconoRAM Time Chip offers a simple solution for storing and retrieving vital data and time
information with minimal hardware. The DS2404 contains a unique lasered ROM, real-time
clock/calendar, interval timer, cycle counter, programmable interrupts, and 4096-bits of SRAM. Two
separate ports are provided for communication: 1-Wire and 3-wire. Using the 1-Wire port, only one pin is
required for communication, and the lasered-ROM can be read even when the DS2404 is without power.
The 3-wire port provides high-speed communication using the traditional Dallas Semiconductor 3-wire
interface. With either interface, a strict protocol for accessing the DS2404 ensures data integrity. Utilizing
backup energy sources, the data is nonvolatile (NV) and allows for stand-alone operation.
1-Wire is a registered trademark of Dallas Semiconductor.
16-PIN DIP (300 MIL)
16-PIN SO (300 MIL)
16-PIN SSOP (208 MIL)
